[Q] Help required ! PLEASE! (No Network/Unknown IMEI when SIM inserted)

OsamaBT · Sep 15, 2013

Model: LG Optimus G Pro F240s

I was on a custom rom when I started getting no network so I followed the best method to get to stock by a user (using LG flash tool).

I was successful & got back to as stock as possible, Problem:
the IMEI is showing as unknown, only when SIM is inserted !
WCDMA hidden menu settings change & save when there is no sim but with sim inserted they do not change & IMEI is shown as unknown !
Please help.

I have searched a lot but no progress!
I read that if any of you give me the stock efs images for efs for a Optimus F240s then I can restore them back.

"IT`S ALIVE" !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

IM SO HAPPY RIGHT NOW!!!!

Ok , im a noob but i did what others said "impossible"
There was no logic in my method but i didnt gave up.

I used FlashTool.1.0.54 with a Brazilian carrier KDZ(my current Carrier) . - No sucess (i flashed a 989 kdz in my F240L, but i did that to try to recover modem and baseband data)

After that, as i had no sucess, i flashed the korean kdz ( F240L10v from the LGU carrier) but i did not wipe cashes and user data.

When i finished to flash the f240l my signal was back, but i got several crashes from the rom (i clicked "ok" more than 100 time XD ) but managed to enter system (i was kinda blind cos evething was in korean language) and perform a factory reset.

NOW EVETHING WORKS FINE, THANKS LORD !!!!

My advice: Dont give Up, try everything even if u tried it already...try again and again.

I wish you luck !!!!!

You have to be on download mode and your battery needs to be 100% fully charged, otherwise the update will not go thru. Good luck!:good:

Joining the pack here... Please help. Trying to download the Stock ROM for v10V right now. Phone came with 10Z originally or so I think. That's what comes up when I check the IMEI through browser anyway. Tried to put stock 10z and issue unfixed.

Edit:

Cannot download v10V... link from lg-firmware not working.

Anyone who has a copy of it?

m0rc0n · Jan 2, 2014

Fixed it!!! Ahahahaha! :laugh:

Step 1: I installed Stock E980h Panama Firmware. Download it from lg-firmware

Step 2: Installed Stock Original F240L 10z Firmware.

Step 3: Jump, Roll and Jump again becuase it's working now and I dont know why. Ahahahaha!
